Luis Alberto Suárez Díaz (Spanish pronunciation: [ˈlwis ˈswaɾes]; born 24 January 1987) is a Uruguayan professional footballer who plays as a striker for Major League Soccer club Inter Miami. He is regarded as one of the greatest strikers of all time and one of the best players of his generation. Nicknamed "El Pistolero" ("The Gunman"), individually, he has won two European Golden Shoes, an Eredivisie Golden Boot, a Premier League Golden Boot and a Pichichi Trophy. He ranks fourth for the all-time South American men's top goalscorers in international football (69), only trailing Pelé (77), Neymar (79), and Lionel Messi (114). He has also scored over 600 career goals and provided over 300 assists for club and country.

Suárez began his senior club career at Uruguayan club Nacional in 2005. He signed for Groningen the following year, before transferring to Ajax in 2007. There, he won the KNVB Cup and the Eredivisie. In 2011, Suárez signed for Premier League club Liverpool, and won the League Cup in his first full season. In his final season with the club, he produced one of the most dominant seasons in Premier League history; he equalled the goalscoring record for a 38-game Premier League season, with Liverpool finishing just two points behind Manchester City in the title race. That summer, Barcelona signed Suárez £64.98 million (€82.3 million adjusted for inflation), making him one of the most expensive players of all time.

Suárez was part of a dominant attacking trio dubbed MSN, alongside Messi and Neymar. He won the treble of La Liga, the Copa del Rey and the UEFA Champions League in his first season, and in his second season he scored 59 goals in 53 matches as Barcelona won the double. He was named in the FIFA FIFPro World11 and awarded the Pichichi Trophy and his second European Golden Shoe, becoming the first player since 2009 to win both awards other than Messi or Cristiano Ronaldo. He was also the first player ever to simultaneously lead La Liga in goals and assists. In 2020, he signed for Atlético Madrid, where he was instrumental to the club's La Liga title triumph in his debut season.

At international level, Suárez is Uruguay's all-time leading goalscorer, and formerly held the title of being the highest goalscorer in CONMEBOL FIFA World Cup qualifiers before being surpassed by Messi. He has represented his nation at four editions of the FIFA World Cup and five editions of the Copa América, as well as the 2012 Summer Olympics and the 2013 FIFA Confederations Cup. He was named in the 2010 World Cup All-Star Team and won the 2011 Copa América, where he was awarded Best Player. Outside of his football credentials, Suárez has been a source of controversy throughout his career, including a goal-line handball clearance against Ghana at the 2010 FIFA World Cup, biting opponents on three occasions, accusations of diving, racist incidents, and spitting incidents.

Suárez lived his early years at the Cerro neighbourhood in Salto, where he played youth football at Sportivo Artigas. At age seven, he moved with his family (parents and six brothers) to Montevideo, where he played youth football at Urreta. When he was a child, a car ran over his foot, breaking the fifth metatarsal bone. In spite of the injury, he continued to play.

Suárez joined local side Nacional's youth team at age 14. At age 16, Suárez headbutted a referee after showing his discontent following a red card, although a sports editor claimed he "accidentally fell into the referee". One night, he was caught drinking and partying, prompting his coach to threaten he would never play unless he started playing football more seriously. In May 2005, at age 18, Suárez made his first-team debut against Atlético Junior in the Copa Libertadores. He scored his first goal in September 2005 and helped Nacional win the 2005–06 Uruguayan league with 10 goals in 27 matches.^{[citation needed]}

Suárez was found by a group of scouts from the Dutch club Groningen when they were in Uruguay to scout another player. As they watched, he won and converted a penalty and scored a "wonder goal" against Defensor. After watching only that match, the scouts approached Suárez and said they wanted to buy him, and after the season, Groningen paid Nacional €800,000 for him. Suárez was thrilled to go to Europe because his then girlfriend, and now wife, Sofía Balbi, had moved to Barcelona; they had maintained a long-distance relationship for a year and he wanted to move closer to her.

Suárez was 19 years old when he joined Groningen. Initially, Suárez struggled because he could not speak Dutch or English, and he played on the second team to adjust to the Dutch game. His teammate and fellow Uruguayan, Bruno Silva, and his teammate Rùfson, helped him settle into living in the Netherlands and playing for a new team. He worked hard to learn Dutch and his teammates respected him for his efforts with the language. Suárez scored goals for Groningen, but he also had disciplinary problems; in one five-game stretch in January 2007, he scored four goals but received three yellow cards and one red card. Suárez especially made his mark in a 4–3 home win over Vitesse, when with ten minutes to go he subsequently won a penalty and scored two goals. Suárez ended with 10 goals in 29 league appearances to help Groningen finish eighth in the 2006–07 Eredivisie. He also scored in a 4–2 loss to Serbian club Partizan in his European debut on 14 September 2006.
